一、漏洞信息
漏洞编号：CVE-2024-47613
漏洞归属组件：gstreamer1-plugins-good
漏洞归属的版本：1.16.2,1.19.3,1.20.3
CVSS V3.0分值：
BaseScore：9.8 Critical
Vector：CVSS：3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
漏洞简述：
GStreamer is a library for constructing graphs of media-handling components. A null pointer dereference vulnerability has been identified in gst_gdk_pixbuf_dec_flush within gstgdkpixbufdec.c. This function invokes memcpy, using out_pix as the destination address. out_pix is expected to point to the frame 0 from the frame structure, which is read from the input file. However, in certain situations, it can points to a NULL frame, causing the subsequent call to memcpy to attempt writing to the null address (0x00), leading to a null pointer dereference. This vulnerability can result in a Denial of Service (DoS) by triggering a segmentation fault (SEGV). This vulnerability is fixed in 1.24.10.
